RSU Module Compatibility with MAX 10 Devices

Hi,

I'm planning to use the RSU module, adapting it slightly by replacing the I²C interface and tailoring it to my needs.

https://www.intel.com/content/www/us/en/design-example/714746/intel-max-10-fpga-i2c-remote-system-update-design-example.html

However, I encountered a significant issue in the current implementation.
In the slave-side top-level file FLASH_LOADER.v, there's an instantiation of MAX10_REMOTE_UPDATE.v, which in turn instantiates the following module:

fiftyfivenm_rublock RuBlock (

.clk (Clock),

.shiftnld (RuShiftNLd),

.captnupdt (RuCaptNUpdt),

.regin (RuDin[0]),

.rsttimer (WatchdogKick[4]),

.rconfig (RuConfig),

.regout (RuDout)

);

The problem is that fiftyfivenm_rublock is not supported by the MAX 10 device family.
This raises a few questions:

  • Do you know of any implementation of this RSU module that works on MAX 10 devices?
  • If so, how was this achieved despite the apparent incompatibility?
  • Since this RSU module seems intended for MAX 10 devices, am I missing something?


I’d appreciate any clarification you can provide.


Thanks,
Mkmk

    Hello,


    MAX10 dont support fiftyfivenm_rublock module. Only supported by Stratix V or Cyclone V series.


    You may refer to below working design example build specifically for MAX10:


    The design used : On-chip flash IP, Dual Configuration IP, NIOS II processor etc.

    On MAX10, RSU is managed via On-chip flash IP, which allows writing to the CFM sectors.

    Please refer to AN741 for more details.


    regards,

    Farabi
